SAMUEL T. HOENER, OF SLATER, MISSOURI;

DRIVING AND STEERING MECHANISM FOR CULTIVATORS.

Application filed February 27, 1922. Serial No. 539,537.

To all whom it may concern:

Be it known that I, SAMUEL T. HOENER, a citizen of the United States, residing at Slater, in the county of Saline and State of Missouri, have invented new and useful Improvements in Driving and Steering Mechanism for Cultivators, of which the following is a specification.

This invention relates to driving and steering mechanism for cultivators of the power driven type, and the object is to provide particular means for imparting movement from the line shaft, through shaft ele- 'ments mounted on the front axle, to gearing directly associated with the knuckles and their spindles, and to provide steering means adapted to this construction.

' A further object is to provide an axle construction suitable for the drive herein specified,

With the foregoing and other objects, the invention consists in the novel construction and arrangement of elements described and claimed, it being understood that modifications may be made within the scope of the ,claims, without departing from the spirit of the invention.

In the drawings, Figure 1 shows the machine in side elevation; Figure 2 is a top plan view; Figure 3 is taken on line 33 of Figure 2, but is chiefly in elevation, and shows the steering mechanism the axle and part of the frame; Figure 4 is on line 44 of Figure 2, and shows the steering means from the opposite side of the axle; Figure 5 is a top plan view showing a rear fork and wheels mounted thereon, for single row work; Figure 6 is a detail view of the band brake structure.

The motor 10 is mounted between the frame elements 11 and 12, the latter supporting a radiator 13. The line shaft 15 extends to the transmission casing shown conventionally and designated 16.

The housing for the differential gearing is designated 18, and the elements of the front drive shaft are shown at 19 and 20. These shaft elements are mounted above the front arched axle 21 of substantially the form shown. Braces 22 extend rearwardly and connect with the cultivator beams 24 and 25, other braces 26 having connection with the cultivator beams 27 and 28.

On the outer ends of each of the shaft members 19 and 20 is mounted a gear wheel 30 meshing with a gear wheel 31 on the vertlcal shaft 32 which extends through knuckle blocks 33, the shaft ha-ving keyed thereto a pinion 34 meshing with the gear wheel 35 carried by ground Wheel 36 of the cultivator.

The shaft 32 is journaled in bearings 37 and 38 in the yoke member 39, one of these yokes being carried by each end of the arched axle 21. The manner of imparting drive from line shaft 15 to the front wheels 15 therefore apparent, and in order that the operator may hold either front Wheel stationary in making a short turn, particular brake mechanism is provided.

The shaft elements 19 and 20 are provided respectively with brake wheels 41 and 42 with Which brake bands 43 cooperate. These shoes are controlledthrough pedals 44 and 45, rods 46'and 47 and the. connections illustrated.

A steering wheel 50 is mounted on the shaft or steering column 51, and rigidly mounted near the end thereof is an arm 52 having connection ,with rod 54, which in turn is connected with radius rod 55 at the point 56.

Arms 58 are connected with opposite ends of rod 55, this being a pivotal connection, and the arms are rigidly connected with shafts 59, each shaft operating a'rod 60 to which it is connected by the arm 61. An arm 62 carried by each knuckle block 33 has pivotal connection with rod 60, permitting the operator to control the front wheels.

On'the beam 64 the drivers seat 65 is mounted, and a fork 66 (Fig. 5) may be pivotally mounted at 67 on the beam and provides bearings for wheels 68 and 69, this construction being employed for single row work. A lever 70 at the rear of the drivers seat carries an element 71 constituting a locking device for engaging the teeth 72 of the central element of the fork, thereby making it possible to retain the latter in the position desired. For two-row work. I employ the form of device shown in Figure 1 and including a fork 75 mounting a single wheel 76. the position of the mounting means being determined by the position of the locking device 76'. The arched axle is to be of the length required for a one row cultivator or a two-row machine, and it should be added that the steering rods are to be mounted in the rear of the axle.

The connections between the rods and the knuckle blocks permit the wheel to be turned at the angle ofabout. forty-five degrees. Having thus described my invention, claim:

1. lln a device of the class described, a shaft comprising elements in axial alignment, driving means for the shaft elements, an axle mounting said shaft elements, a yoke member carried by the axle and providing upper and lower bearings, a knuckle block, a vertical shaft extending through the block and extending upwardly beyond the upper bearing of the yoke, gearing for driving this shaft from one ofthe shaft elements before named, a pinion carried by the vertical shaft, a gear wheel meshing therewith, a vehicle wheel mounting said gear wheel last named, an arm carried by the knuckle block, a vertical shaft and mounting means therefor, a plurality of pivotally connected elements normally at apanse? proximately right angles with each other for controlling the arm from the vertical shaft, and means for partly rotating said vertical 1 shaft 2. In a device of the class described, an axle, yoke members carried by the outer ends thereof, knuckle blocks and means for mounting the blocks for rotation with reference to the yokes, ground wheels and driving means therefor, an arm carried by each of the blocks, a vertical shaft and mounting means therefor, a plurality of pivotally connected elements normally at approximately right angles with each other for connecting the shaft with said arm for moving the arm and block upon the partial rotation of the shaft, a radius rod and an arm connecting the latter with the shaft, and means controlling the radius rod.

In testimony whereof ll afix my signature.
